I was just reading this article which states that two Unions one in the UK and the other in the US are on the brink of joining forces, now i not sure if this is common, but i was thinking what it would be like with a worldwide super-power Union to resist globalisation and big business.

Maybe this will be the step forward on Marx's ladder of the Workers Power or the turning factor some time in the future to ending exploitation of workers abroad in poorer countries.
